RE: side-by-side upgrade

Hi Mike

Did the BP actually just do a restore or did they do a mixed release
migration ? Your description of the process seems to have some gaps to me
which might explain why the BP wants to go this route.

What release are you currently on ?

Subject: side-by-side upgrade

We purchased a new power 6 system as an upgrade and are able to run both the
old and new systems side by side. Our BP installed V5R4M5 on the new system
and then we did a full save (option 21) on the current system and a full
restore to the new. They the BP installed the most recent PFTs. Total time
to backup was about 4 hours, total time to restore was about 4 hours. Adding
in the PFTs added another 6. 14 hours total downtime to make the switch. We
are going to check out the new system to be sure everything is there and
running and looks good and then schedule a weekend to make the final
cutover.  Since the only thing that is going to change is our data could we
safely do a save (option 21) and then just restore userprofiles and our
libraries? BP would like to blow away everything and start from installing
V5R4M5 again, then a full restore and all the PFTs again. Looking to save
that extra 6 hours of downtime.
